Sample WY-TOPP Science Grade 4 Practice Questions

Try these sample questions to review concepts for the WY-TOPP Science Grade 4 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A student rolls two identical wooden balls down a hill. Ball A rolls slowly, while Ball B rolls quickly. Which statement correctly compares their kinetic energy?
A.Ball A has more kinetic energy because it is moving slower.
B.Ball B has more kinetic energy because it moves at a higher speed.
C.Both balls have the same kinetic energy because they have equal mass.
D.Neither ball has kinetic energy while rolling down a slope.
Explanation: Kinetic energy depends on speed when mass is constant. Since Ball B is moving faster than Ball A, Ball B has greater kinetic energy.
2A toy car rolls down a high ramp and moves faster than a toy car rolling down a low ramp. What evidence does this provide about speed and energy?
A.Speed decreases as an object gains kinetic energy.
B.Faster moving objects carry more energy of motion.
C.Ramp height does not affect how fast a car moves.
D.Energy disappears when a toy car stops at the bottom.
Explanation: Observations showing that a faster toy car has greater impact capability support the concept that higher speed corresponds to greater kinetic energy.
3When a moving bowling ball hits wooden pins, the pins knock backward and make a loud crashing sound. What happens during this collision?
A.Energy is destroyed when the ball touches the pins.
B.Energy transfers from the moving ball to the pins and air.
C.The pins create new energy that stops the bowling ball.
D.No energy transfer occurs because pins are nonliving.
Explanation: During a collision, energy of motion transfers from the moving ball into the pins (causing them to move) and into the surrounding air as sound.
4A student plucks a tight rubber band stretched across an empty shoe box. The rubber band vibrates rapidly and produces a musical sound. What causes the sound?
A.Vibrations transfer energy into the air as sound waves.
B.The shoe box creates electricity when touched.
C.Air inside the box stops all vibrations immediately.
D.Rubber bands release light energy when plucked.
Explanation: Sound is produced when vibrating objects transfer kinetic energy to nearby air particles, creating sound waves that travel to our ears.
5A student shines a flashlight onto a smooth wall in a dark room. Which statement best explains how light travels from the flashlight to the wall?
A.Light travels in curved loops through dark air.
B.Light travels in straight paths called light rays until it strikes an object.
C.Light stops moving as soon as it leaves the flashlight lens.
D.Light spreads out only after bouncing off three different walls.
Explanation: Light travels outward from a source in straight paths (rays) until it strikes a surface, where it can be absorbed, reflected, or transmitted.
6A simple circuit consists of a battery, two copper wires, and a light bulb. When all connections are tight, the bulb lights up. What must be true about this circuit?
A.The circuit is open and electrical current cannot flow.
B.The circuit is closed, forming a continuous path for electric current.
C.Energy flows only when the battery is completely disconnected.
D.Copper wires block electricity from reaching the light bulb.
Explanation: An electric circuit must form a complete, closed loop for electric current to flow continuously from the battery to the light bulb.
7Why can a student see their clear reflection in a smooth glass mirror but not on a rough wooden tabletop?
A.Smooth mirrors reflect light rays in an orderly, parallel direction.
B.Rough wood absorbs all light and produces no reflections at all.
C.Mirrors create light rays inside the glass without an external source.
D.Wood reflects light rays in perfectly straight lines toward the eyes.
Explanation: Smooth mirror surfaces bounce light rays off evenly at identical angles (regular reflection), forming a sharp image. Rough surfaces scatter light in many directions.
8On a chilly Wyoming winter morning, a student rubs their gloved hands together quickly. Their gloves feel warm. What energy transformation is taking place?
A.Electrical energy transforms into chemical energy.
B.Motion energy (kinetic energy) transforms into thermal energy (heat).
C.Light energy transforms into sound energy.
D.Thermal energy transforms into stored potential energy.
Explanation: Friction created by rubbing hands together transforms kinetic energy (motion) into thermal energy (heat).
9A student drops a small pebble into a calm pond. Ripples spread outward in expanding circles across the water surface. What do these ripples represent?
A.Water moving permanently away from the center without returning.
B.Waves carrying energy outward across the water surface.
C.Heat energy melting ice at the bottom of the pond.
D.Sound particles turning into liquid water droplets.
Explanation: Water ripples are surface waves that transfer kinetic energy outward from the pebble impact site through the water medium.
10A student pulls back the elastic string of a toy archer bow and holds it still. When released, the arrow flies forward. What describes the energy before release?
A.The pulled string holds stored potential energy.
B.The still arrow has maximum kinetic energy of motion.
C.Energy is completely absent until the arrow hits a target.
D.The string creates light energy while held still.
Explanation: Stretching the elastic bowstring stores energy as elastic potential energy. Releasing the string transforms stored potential energy into kinetic energy.

About the WY-TOPP Science Grade 4 Exam

The WY-TOPP (Wyoming Test of Proficiency and Progress) Summative Science assessment for Grade 4 is Wyoming's required annual statewide science test, administered by the Wyoming Department of Education during the spring window (April 14 - May 8 in 2026). It is built on the 2026+ Science Assessment Blueprint approved by the State Board of Education on September 19, 2024 and aligned to the reduced 2023 Wyoming Science Content and Performance Standards, which became operational on WY-TOPP in the 2025-26 school year. The blueprint weights Physical Science at 58-64%, Life Science at 22-28%, and Earth and Space Science at 10-15%, with engineering and design embedded inside Physical Science. Because the standards were reduced, WDE ran a fresh data-validation and standard-setting process for spring 2026 science results, released in fall 2026, and individual student reports for science no longer include domain-level reporting. Please note: this practice bank is an English-language multiple-choice study adaptation created by OpenExamPrep, not an official test form or a simulation of the real item formats.

Exam sponsor: Wyoming Department of Education (WDE). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

WY-TOPP Science Grade 4: Suggested Study Strategy

1Physical Science carries the most weight by far. Spend most of your review on energy conversion, waves, and information transfer rather than spreading effort evenly across the three strands.
2Practice describing a wave by its amplitude (how tall) and its wavelength (how far apart the peaks are), and be ready to explain how a passing wave makes a floating object bob up and down.
3For 4-PS4-3, look at how patterns carry a message: Morse code, binary pulses, drumbeats, and flashing lights all encode information in repeated on/off patterns.
4Energy conversion questions ask you to compare designs. Practice judging which device better meets stated criteria and constraints, and what you would change to improve it.
5For Life Science, connect a structure to the job it does: roots take in water, thick fur traps warm air, hollow bones reduce weight for flight.
6For Earth and Space Science, remember that in undisturbed layers the deepest rock is oldest, and that a fossil tells you what the environment was like when that layer formed.
